PROCESS OF MANUFACTURING HORNS.

SPECIFICATION forming part of Letters Patent N 0. 769,410, dated Septemberfi, 1904.

I Application filed February 18, 1904.

To all whom. it may concern:

Be it known that I, EDWARD A. SCHOETTEL, a citizen of the United States, and a resident city and State of New York, have invented a new and useful Process or Method for the Manufacture of Megaphone and Similar and exact description, reference being had to the accompanying drawings, in which- Figure 1 illustrates an elevation of the former or block on which the horn is made,

or similar material in position thereon which, with others, are to form the horn. Fig. 2 illustrates an end view of that which is shown in Fig. 1 on the line 11 of that View. Fig. 3 illustrates an elevation similar-to that shown in Fig. 1, showing, however, all of the pieces or gores also of material which, with the others shown, are to form the horn, in place on the former, covering the spaces between the longer gores. Fig. at illustrates an end view of that which is shown. in Fig. 3, taken on the line 3 3 of that figure. Fig. 5 illustrates a'detail showing the notch in the lower end of the gores, whereby they are held in position on the former. Fig. 6 illustrates an elevation of the apparatus whereby the gores are all drawn forcibly down to position and held there until drier.

A represents the conical or tapering former or block upon which the horn is made up from a series of tapered or gore-shaped pieces D D D D of paper or similar material. The former may be and usually is made of wood, although any other suitable material may be used. Its exterior shape determines the shape of the horn.

B B are a series of catches, which may be like very large headed nails, driven into or fastened to the former at stated intervals near its larger end, as shown, in such positions that a notch C (see Fig. 5) made in the lower edge of each of the gores will fit under the appropriate nail, and thereby that end of the gore will be held against lateral movement during "have been applied to the her stated the former is the process of applying them upon the former.

The upper ends of the gores (see Figs. 1 1

Serial No. 194,161. (No model.)

and 2) are confined adhesive material applied to them where they partly by glue or other overlap and also by a cord E, which is tightly tied about their applied to the former.

F is a round bearing, preferably grooved, as

upper ends, where they are frame, which is suitably braced and provided with suitable tension devices, such as the crossbars K K. At the upper end of'the' bar I there is'an open-ended semicircular notch or journal, adapted to receive the small end of the former with the tied ends of the gores thereon, and on the upper end of the other bar, I, there isanother open-ended journal, adapted to receive the bearing F. V

L is a small rope, which may be about the size of an ordinary clothes-line or somewhat larger, if preferred, and it is of such length as to make successive coils, preferably touching each other, the whole length of the gores and preferably one or two additional coils. I prefer that at the smaller end feet of material, such as pigskin or belt lacing M, be substituted for the rope, but attached to it, because such material, being more pliant and self-adjusting than the rope, will more satisfactorilydraw the small and relativelystifi edges of the narrower part of the gores into position than the rope will, and also some part of the pigskin lacing necessarily, or at least preferably, rests within the journal, be ing wound tightly thereon under the strain of the crank in such manner that the former revolves on it, and I have found that the pressure of this operation on the pliant lacing secures a better finish to the small end of the horn than if the rope were used and also that the lacing will not 'wear or fray out as much as the rope will.

The operation is as follows: After the gores former in the 1 manlifted from its primary support and placed in the winding-frame. (Shown in Fig. 6.) Then the crank is applied "55. shown, fastened centrally on the base of the i of the journal part is a to the squared boss G, and the end of the lacing M is firmly attached to the small end of the former, preferably just at the ends of the gores or slightly beyond them. Then one operative forcibly turns the crank which another directs and applies tension upon the rope and lacing. In this way the strain may be uniform or varied, as circumstances require and as observed, during the winding operation to draw all the edges of the several gores from their angular position (shown in Figs. 2 and 4:) into the requisite circular form shaped product. If the glue or other adhesive material has at all set or chilled before the forming pressure is applied to the gores, then I subject the same to a blast of steam, which will soften the adhesive material and eer Warmers cor and forcible pressure of a single flexible and elastic binding device which is wound upon them under tension as the former revolves.

2. The process described in the manufacture of horns, consisting in cutting the material of which the horn is to be made into goreshaped pieces,detachably attaching said pieces to an interior former, whereby circumferential movement of one relative to the other is prevented, the edges of said pieces overlapping, applying adhesive material between the overlapping edges, revolving the interior sive material is still soft and subjecting the parts composing the horn to the continuous and forcible pressure of a single flexible and elastic binding device, which is wound upon them under tension as the former revolves,

to makeahandsomely-flnished and uniformlyformer and the pieces with it while the adherender all parts pliant, so that they will readily the winding of the binding device upon the 20 respond to the pressure exerted by the lacing gore-shaped pieces commencing at the small 8 5 and rope, or by the rope alone if the lacing is not used.

Obviously lacing may be used throughout, if preferred, and any equivalent material other than the rope or lacing may be substituted therefor.

After the compression or forming of the gores has been finished by winding the rope or its equivalent on them, as shown, then the end of the rope is suitably fastened and the whole set aside to dry in its then condition. Meantime other horns may be made on other formers. hen dry, the rope and lacing are unwound and removed, and then the edges of the gores are sandpapered down and the horn is finished in the usual way.

It will be obvious to those who are familiar with this art that many modifications may be made in the details of construction and oper-- ation of the parts. The former may be turned by machinery, and the flexible rope binder may be manipulated in a variety of ways, all, however, within the spirit and embodying the essentials of my process, which consistsin the application upon the gores of the horn while they are held in position and while the adhesive material is yet soft of the pressure of a flexible binding device adapted to apply equal or varying pressures, as desired, upon eachand every part of the gores, irrespective of the shape and size of the horn and of the material of which it is composed.

I claim- 1. The process described in the manufacture of horns, consisting in cutting the material of which the horn is to be made into goreshaped pieces,detachably attaching said pieces to an interior former, whereby circumferential movement of one relative to the other is prevented, the edges of said pieces overlapping, applying adhesive material between the overlapping edges, revolving the interior former and the pieces with it while the adhesive material is still soft and subjecting the 5 parts composing the horn to the continuous end of the horn and progressing towai'd the larger end thereof.

3. The process described in the manufacture of horns, consisting in cutting the material of which the horn is to be 'made into goreshaped pieces,detachably attaching said pieces to an interior former, whereby circumferential movement of one relative to the other is prevented, the edges of, said pieces overlapping, applying adhesive material between the overlapping edges and winding under tension continuouslyapplied always in the same direction upon the parts composing the body of the horn, while they are supported in position upon the former, a flexible and elastic binding device, which is wound upon the said pieces commencing at the small end and extending toward the larger end, said binding I device being provided with means whereby its tension may be varied at will.

L. The process described in the manufacture of horns, consisting in cutting the material of which the horn is to be made into goreshaped pieces,detachably attaching said pieces to an interior former, whereby circumferential movement of one relative to the other is prevented, the edges of said pieces overlapping, softening adhesive material previously applied between the overlapping edges by the application of steam thereto, revolving the interior former and the pieces with it while the adhesive material is plastic and adhesive and subjecting the parts composing the horn to the continuous and forcible pressure of a single flexible and elastic binding device which is wound upon them under tension as the former revolves.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWARD A. SCHOETTEL.
